John McCain's temper is well documented. He's called opponents and colleagues "shitheads," "assholes" and in at least one case "a fucking jerk."

But a new book on the presumptive Republican nominee will air perhaps the most shocking angry exchange to date.

The Real McCain by Cliff Schecter, which will arrive in bookstores next month, reports an angry exchange between McCain and his wife that happened in full view of aides and reporters during a 1992 campaign stop. An advance copy of the book was obtained by RAW STORY.

Three reporters from Arizona, on the condition of anonymity, also let me in on another incident involving McCain's intemperateness. In his 1992 Senate bid, McCain was joined on the campaign trail by his wife, Cindy, as well as campaign aide Doug Cole and consultant Wes Gullett. At one point, Cindy playfully twirled McCain's hair and said, "You're getting a little thin up there." McCain's face reddened, and he responded, "At least I don't plaster on the makeup like a trollop, you vaginal distortion." McCain's excuse was that it had been a long day. If elected president of the United States, McCain would have many long days.
